摘要： A head unit, in which unit head rows are formed by respectively arraying unit heads in parallel on both sides of a transmission substrate. The head unit includes a first liquid fluid channel that is disposed on a first side of the transmission substrate and a second liquid fluid channel that is disposed on a second side of the transmission substrate. The unit heads are provided with a flexible cable. A first head fluid channel sandwiches the flexible cable and is provided on a side that is opposite a transmission substrate side. A second head fluid channel is provided on the transmission substrate side. The first head fluid channel is in communication with a first liquid fluid channel on a surface side on which the unit heads are disposed. The second head fluid channel straddles the transmission substrate and is in communication with a second liquid fluid channel on a surface side that is opposite the unit heads.

摘要： A liquid ejecting apparatus is provided which can suppress bubbles from remaining in liquid flow paths. The liquid ejecting apparatus includes a head that includes a flow path member in which a plurality of ink flow paths are formed, a head main body to which ink is supplied form the flow path member and which ejects the ink to a recording sheet, and a moving element that causes the head to perform a reciprocating moving motion on the recording sheet in the X direction. In the plurality of ink flow paths, the longest ink flow path has the smallest Y direction component on an XY surface (a horizontal surface) of the plurality of ink flow paths.

摘要： A flow channel member to which an ink cartridge is removably mounted has a sealing member made of an elastic material around the entire periphery of an installation section of a flow channel member main body. The sealing member is integrally formed of: a top plane portion, where an end face of a leg portion abuts the top plane portion so as to define an enclosed space between an inner peripheral surface of the leg portion and an outer peripheral surface of the installation section; and an inner leg portion and an outer leg portion extending from edges of the top plane portion along the longitudinal axis of the installation section, and having end faces, abutting the flow channel member main body. Furthermore, the sealing member has curved thicker portions.
